How to add UITableview in UIAlertController in iOS8?

问题

Till iOS7 in Custom view we can put tableview in alert as per below picture.

But in iOS8 UITableview is not working. I can put it in tableview but the tableview is not scrolling and not detecting any click on any cell.

So, how do I implement this type of AlertController ?

回答1:

Please try below code with custom view and animations

Test.h

#import <UIKit/UIKit.h>

@interface Test : UIView <UITableViewDataSource,UITableViewDelegate>
{
    UITableView *table;
}

- (id)initWithFrame:(CGRect)frame Array:(NSArray *)ArrayValue;
- (void)showInView:(UIView *)aView animated:(BOOL)animated;
- (void)fadeOut;

@end

Test.m

- (id)initWithFrame:(CGRect)frame Array:(NSArray *)ArrayValue
{
    if (self = [super initWithFrame:frame])
    {
        aryType = ArrayValue;
        table = [[UITableView alloc] initWithFrame:CGRectMake(15, 0, 320, 380) style:UITableViewStylePlain];
        table.dataSource = self;
        table.delegate = self;
        [table setSeparatorInset:UIEdgeInsetsZero];
        table.showsVerticalScrollIndicator = YES;
        [self addSubview:table];
    }
    return self;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return aryType.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.selectionStyle = UITableViewCellSelectionStyleGray;
    }
    cell.textLabel.text = [aryType objectAtIndex:(indexPath.row)];
    cell.textLabel.font = [UIFont fontWithName:@"Avenir Next" size:16];
    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    NSLog(@"select");
}

- (void)fadeIn
{
    self.transform = CGAffineTransformMakeScale(1.3, 1.3);
    self.alpha = 0;
    [UIView animateWithDuration:.35 animations:^{
        self.alpha = 1;
        self.transform = CGAffineTransformMakeScale(1, 1);
    }];
}

- (void)fadeOut
{
    [UIView animateWithDuration:.35 animations:^{
        self.transform = CGAffineTransformMakeScale(1.3, 1.3);
        self.alpha = 0.0;
    } completion:^(BOOL finished) {
        if (finished) {
            [self removeFromSuperview];
        }
    }];
}

- (void)showInView:(UIView *)aView animated:(BOOL)animated
{
    [aView addSubview:self];
    if (animated)
    {
        [self fadeIn];
    }
}

At last from your viewcontroller call this view as per below code
Viewcontroller.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSArray *aryType = [[NSArray alloc] initWithObjects:@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10", nil];
    [self showPopUpWithTitle:@"Title" arrOptions:aryType xy:CGPointMake(16, 150) size:CGSizeMake(287, 134)];
}

- (void)showPopUpWithTitle:(NSString *)popupTitle arrOptions:(NSArray *)arrOptions xy:(CGPoint)point size:(CGSize)size
{
    testView = [[Test alloc] initWithFrame:CGRectMake(15, point.y, size.width, 200.0) Array:arrOptions];
    [testView showInView:self.view animated:YES];
}

Courtesy StackOverFlow users i was able to do this task... here is my code...

 UIViewController *controller = [[UIViewController alloc]init];
UITableView *alertTableView;
if (array.count < 4) {
    CGRect rect = CGRectMake(0, 0, 272, 100);
    [controller setPreferredContentSize:rect.size];
    alertTableView  = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 272, 100)];
}
else if (array.count < 6){
    CGRect rect = CGRectMake(0, 0, 272, 150);
    [controller setPreferredContentSize:rect.size];
    alertTableView  = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 272, 150)];
}
else if (array.count < 8){
    CGRect rect = CGRectMake(0, 0, 272, 200);
    [controller setPreferredContentSize:rect.size];
    alertTableView  = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 272, 200)];
}
else{
    CGRect rect = CGRectMake(0, 0, 272, 250);
    [controller setPreferredContentSize:rect.size];
    alertTableView  = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 272, 250)];
}

alertTableView.delegate = self;
alertTableView.dataSource = self;
alertTableView.tableFooterView = [[UIView alloc]initWithFrame:CGRectZero];
[alertTableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];
[alertTableView setTag:kAlertTableViewTag];
[controller.view addSubview:alertTableView];
[controller.view bringSubviewToFront:alertTableView];
[controller.view setUserInteractionEnabled:YES];
[alertTableView setUserInteractionEnabled:YES];
[alertTableView setAllowsSelection:YES];
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];
[alertController setValue:controller forKey:@"contentViewController"];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action) {

}];
[alertController addAction:cancelAction];
[self presentViewController:alertController animated:YES completion:nil];
